After a loss, I have the urge to get back into a trade and double the size. And if another loss happens. I'll do it again.
Is it the idea that it's not possible to have another loss in a row
or that I don't want to be at a loss for the day that makes me
jump into trades without any edge.
How does everyone have the discipline to sit on their hand until
their edge appears? Do you ever get pissed off at a trade and
jump in again with double size only to get run over again?

It is only true if there is INDEPENDANCY as for probability law and it is not the case here and there can be several reasons - but I won't extend by giving a lesson on probability.
